Ecology
Diet
It is well known for its diet, which consists primarily of ripe
Reproduction
Details of the breeding habits of this species, certainly in the wild, are very limited due to the secretive nature of this species. The optimum egg-laying time for this species is known to be between July and October, when a clutch of up to 11 eggs will be laid. Rather than digging a nest, the most likely place for this species to lay eggs is thought to be in tree hollows, where they also spend much of their days resting. Young are often observed at their smallest in May to July, and as such estimates of incubation time lay at around 300 days. In captivity, however, incubation has been recorded over 219 days.[5]

In captivity
This species is not widely kept in captivity, which is possibly partly because it is rarely bred successfully. Among others, this species is on display at the following zoos outside the Philippines:
- Los Angeles Zoo
- Oklahoma City Zoo and Botanical Garden
- Protvin Krokozoo[6]
- Wingham Wildlife Park[6]
- Brookfield Zoo[7]
- San Diego Zoo[8]
- Bronx Zoo
- Fresno Chaffee Zoo
One Philippine zoo, Avilon Zoo, has achieved successful breeding of this species. For many years, the only report of a breeding outside of the Philippines was a single baby hatched at the Dallas Zoo in 1994, until the LA Zoo hatched them for the first time in 2015.[9] Dallas gave their two female monitors to the Oklahoma City Zoo in May 2013.
